When girl (or guy) is blowing a (another) guy as the guy is about to cum he grabs her (or his) head and shoves it down his cock so that she (he) cannnot pull away, and chokes on the cum and it goes out her (his) nose, with the cum falling out of her (his) nose and mouth it makes her (him) look like a dragon, and after pulling shit like that you bet she (he) will be an Angry Dragon!

the sexual manouvere in which the gentleman unloads in the females or males, (depending on sexual preferance) mouth....after which slaps the female squarely in the back of the head...releasing the load through the nostrils. Thus the female is angry and is blowing cum like a dragon.
